STUDENTS LAM P.

SPECIFICATION forming part ofLetters Patent No. 270,719, dated January 16, 1883. Application filed December 1, 1882. (No model.)

To all whom it may concern Be it known that I, ALBERT ANGELL, of East Orange, in the State of New Jersey, have invented an Improvement in Students Lamps, of which the following is a specification.

Lamps have been in adewith a globe or shade holder surrounding and connected with the chimney holder, and in Argand lamps the chimney-holder has been removable from the burner for lighting or trimming, as seen in LettersPatent Nos. 240,763 and 247,580.

In students lamps that are provided with shades there is considerable trouble in trimming and lighting, because the shade and the chimney have to be lifted off separately and then replaced, and sometimes the base of the chimney has upon it a thin film of oil, which greases anything upon which it is placed.

I The object of my presentinvention is to sustain the chimney in a students lamp by a connection to the, standard and independent of the burner, so that the lamp-burner may be lowered from the chimney, or the chimney and shade raised from the burner for lighting or trimming, and the reverse when the chimney and burner are brought together. By this improvement the parts are supported from the standard independently of each other, and the lighting andtrimming are much more easily accomplished than heretofore.

In the drawings, Figure 1 is a side elevation of a students lamp with the burner separated from the chimney. Fig. 2 is a plan of the chimney holder and shade -holder, and

Fig. 3 shows a spring applied to the stock of the shade-holder for sustaining the holder and chimney when the latter is separated from the 4 burner.

aforesaid patents.

The base a, standard b, reservoir 0, oil-tube d, burner c, and shade or globe holder f are of the usual character employed in students lamps.

The chimney holder or springs It may be separate from the cone or deflectort', as shown or they may be connected together, as in If they are connected toceive their support from the same source as the shade or globe holderfthrough the medium of one or more arms, at, extending from the shade-holder or the stock of said shade- -holder to the chimney-holder.

The stock 0 of the shade-holder is not supported by the oil-pipe or a socket thereon, as most generally employed, but it is supported by the standard I). I either use aclampscrew, as shown at k in Figs. 1 and 2, or a frictionspring at the eye of the stock surroundingthe standard, as in Fig.3, so as to produce sufficient friction for sustaining the shade and chimney when raised up to separate the chimney from the burner or for holding the chimney and shade while the lamp and its burner are lowered to separate the latter from the chimney.

I provide a guide-rod, r, fastened at its lower end to the oil-tube and-going through a hole in the stock of the shade ring. This serves to bring the chimney-holder base properly into place when the chimney and burner are brought together.

The base of the cone or the gallery-surrounding the wick-tube is to be made slightly flaring at its upper edge to facilitate the guiding of the base of the chimney to its proper place.

In place of the rod 1", the standard may be prismatic; or it may have a groove in it or a rib upon it, the sliding portion of the shadeholder stock and of the lamp being made to lit the standard and be guided by it.

I claim as my invention-- 1. The combination. with the base, standard, reservoir, and burner in a students lamp,

'of. a shade or. globe holder and a'chimneyholder, and means for connecting these to the standard independently of the support for the other portions of the lamp, substantially as set forth.

2. The combination, with the standard, the
